A couple weeks ago I was riding home from work in the dark and cold night. A fellow commuter was up ahead and I wanted to catch up to say hello. While hauling tail, I hit something hard. I don't know if it was a pothole or a rock or what. But 50 yards down the road I noticed my rear tire was flat. Luckily I had a spare tube so thought no big deal. I replaced the rear tube and re-inflated rear tire. I flipped the bike over and went to take off only to realize the front was also flat. And I was out of spare tubes with no patch kit.

I ended up walking the rest of the way home which was approximately 3.5 miles. It was cold and sucked. I now take TWO spare tubes on the bike and a patch kit. Hopefully no more walking home for me. I've noticed the winter season is a lot harsher on tires/tubes than spring, summer, or fall.
